Suppose a neutron, traveling to the right at 1000 m/s, strikes a proton moving upward at 500 m/s. At impact they combine to form a particle called a deuteron. Find the magnitude and direction of the deuteron velocity vector. Take the x-axis along the initial velocity of the neutron and the y-axis along the initial velocity of the proton. Measure the angle from the x-axis.
A positive charge, Q = 45 is placed on the x-axis at x = -1.9 cm. A positive charge which is twice as large is brought from infinity to a point x = +1.9 cm on the x-axis. what would be the speed of the 2*(45) charge at infinity
